Cherokee County is located in northeastern Oklahoma. The 776-square-mile county sits between Mayes and Delaware Counties on the north, Adair on the east, Wagoner and Muskogee on the west, and Sequoyah County on the south.
Cherokee County is a favorite spot for vacationers because of its many recreational areas along the Illinois River, the foothills of the Ozarks, and scenic Tenkiller Lake. The county’s rich history is defined by the Cherokee Nation and its Trail of Tears, which brought a large population of American Indians to the area. The Cherokee Nation’s headquarters share the Cherokee County Seat of Tahlequah.
The latest U.S. Census puts the population of Cherokee County at 46,987.
